There is a lot of buzz these days over a new product called Google (GOOG) Wave. Some are under the false impression that it's the next Twitter, but this new tool from Google is very different. Think of it as a real-time collaboration tool that includes, among its many features, email on steroids.

Greg Dalesandre, Google Wave product manager, in an online video, describes Wave as a "shared space," where users can communicate using text, videos, photos and maps. So you can have a conversation while working on a document with a group of people in another city -- or in another part of the planet. You can both work together in real time using richly formatted text, photos, videos and more. The wave is the shared experience that you are involved with. So you could be working with 10 people and everything you do -- from the conversations you have to the changes you make to a document, will be inside a wave. What's really cool about this is that the wave allows you to rewind, allowing you to see who said what when. Since everything is in real-time -- it's fast.

Most mainstream academic and government economists -- elites, we should note, who are generally well-protected from the vagaries of the real world -- are united in the view that massive federal deficits to fund stimulus programs are not just a good thing but a necessary thing.

Economist J. Brad DeLong, for example, recently raked a journalist over the coals for suggesting deficits might cause long-term harm to the economy. Accusing the journalist of "not doing the arithmetic," the economics professor at the University of California, Berkeley launched into a questionable string of assumptions to reach the dubious conclusion that massive federal borrowing will add a mere $5 per year to every taxpayers' future tax burden.

Warren Buffett, one of the world's richest men and CEO of conglomerate Berkshire Hathaway (BRK.A), once proclaimed that "the banking business is no favorite of ours." The comment came in one of his famous missives to Berkshire's shareholders by way of explaining that financial companies were too risky and opaque for the über-investor's tastes.

But that was in 1990. Today, well-timed investments in banks like Goldman Sachs (GS) and Wells Fargo (WFC) are looking like smart moves for Buffett and Berkshire Hathaway, according to figures contained in the company's quarterly earnings statement released Friday. So are bets on a number of other blue-chip stocks like Johnson & Johnson (JNJ) and Coca-Cola (KO). The company's third-quarter net income nearly tripled to $3.24 billion, or $2,087 per Class A equivalent share, compared with $1.06 billion, or $682 per Class A equivalent share, in the year-ago quarter.

U.S. consumers' efforts to pay down their credit card debts continue. Outstanding U.S. consumer credit fell by $14.8 billion or at a 7.2 percent annual rate in September -- the eighth straight monthly credit decline, the U.S. Federal Reserve announced Friday.

Economists surveyed by Bloomberg News had expected to see a September consumer credit contraction of $10 billion, after a revised $9.9 billion decline in August, and a $19 billion plunge in July. Consumer credit is down 4.7 percent compared to a year ago, and balances have fallen in 12 of the past 14 months.

In September, total outstanding consumer credit, including revolving and non-revolving credit, declined to $2.46 trillion, or by 4.7 percent compared to a year ago, the Fed said. In Q3, total outstanding debt declined at a 6.1 percent annual rate; it fell at 6.6 percent and 3.7 percent annual rates in Q2 and Q1, respectively.

Bears who warn the U.S. stock market has gone too far too fast -- the broad Standard & Poor's 500 index is up 18 percent year to date -- may not get much vindication anytime soon. Investors should see stocks continue to rally as long as corporate profits keep recovering, says market expert Joseph Mezrich (pictured), Nomura Securities International's head of quantitative research.

And the signs look good. The estimated earnings growth rate for the Standard & Poor's 500 during the fourth quarter is 216 percent, according to Thomson Reuters. Even stripping out the volatile financial sector, the other eight out of nine sectors are expected to show a blended growth rate of 7 percent. But that's still double the 3.5 percent economic growth of the U.S. economy in the third quarter. And Mezrich says it's the fact that profit growth is outpacing the U.S. economy that stocks have rallied ahead of an economic recovery.

After weeks of build-up, Verizon Communications's (VZ) Verizon Wireless unleashed its new Google (GOOG)-powered Droid smartphone on Friday, and New York City retailers were selling out of the device -- billed as the first legitimate challenger to Apple's (AAPL) iPhone's first legitimate challenger -- on the first day.

"We're gonna need more phones," Amanda Leavelle, a Verizon Wireless store manager in Manhattan's SoHo neighborhood, said around 2 p.m. "I just checked, and our inventory is running low, so I've got to call for some more."

Fannie Mae's (FNH) report of a third-quarter loss of $19.76 billion and subsequent plea to the federal government for $15 billion in additional aid is sure to intensify a big question that so far has gone unanswered: What can be done to stem the bleeding at the giant mortgage lender and its sibling Freddie Mac (FRE)? Given this week's bankruptcy filing by CIT, which will probably lead to the loss of $2.3 billion in taxpayer money, Fannie Mae's request for another $15 billion will strike many as throwing more good money after bad.

Fannie Mae had previously posted second-quarter losses of $14.8 billion, on top of $23.2 billion of red ink in the first quarter, leading Morningstar equity analyst Matthew Warren to write in a report: "Nothing fundamentally has changed with the situation at Fannie Mae, and we remain quite certain that the equity shares are worthless barring a ridiculous public policy decision on the part of the U.S. government."

When it comes to allocating scarce public resources, large corporations seem to have the upper hand in the US. We already know that many powerful companies, particularly the Wall Street investment banks, having gotten plenty of Washington cash. Now it looks like they're getting first dibs on the scarce H1N1 vaccine as well.

If I remember correctly, last fall the problems with the financial sector nearly cratered the global economy -- what with the $30 trillion in lost stock market value and over a trillion dollars in bank write-offs. As I've written before, Wall Street accounts for 0.057 percent of our population, but because it has given $5 billion to Washington politicians and lobbyists over the last decade, the government poured trillions of dollars into bailing it out after its little collapse last year.

As the full extent of the Galleon Group's insider trading comes to light, its story is starting to resemble something out of the movies. Although Raj Rajaratnam's house has already been compared to the homes in both The Sopranos and Goodfellas, the sad truth is that the real-life criminal ring lacks both the class of Tony Soprano's gang and the gravitas of Joe Pesci's. As details emerge, the whole mess seems to fall closer to the cartoonish excess of Animal House.

The central member of the gang -- the Otter, if you will -- may well be Zvi "The Octopussy" Goffer. Robert Khuzami, director of the Securites and Exchange Commission's Division of Enforcement, noted Thursday that Goffer got his James Bond–originated nickname "because of his reputation for having arms in so many sources of inside information." Goffer used his web of spies to cut trades both at Galleon and at his previous employer, the Schottenfeld Group.

Venture into a supermarket late at night and you're likely to see an employee running a machine used to clean, strip and wax floors. Wander into your local deli and you'll see workers pouring disinfectant over the day's feast.

But ask these workers how they feel and many will confess to cases of headaches, sinus infections, and skin rashes. Which is why janitors and cleaners from the Service Employee International Union have been holding protests outside large grocery stores -- such as Lucky and Safeway (SWY) in Northern California -- to demand that the country's largest supermarket chains ditch toxic cleaning agents and go with greener alternatives.
